Evaluation tasks

The purpose of evaluation is to calculate the quality, value or importance of something. Therefore, the Evaluation tasks have been designed to help users visualize rules through interactive graphics that change according to values.

In Rulex Factory, users are provided with three Evaluation tasks: the Confusion matrix, the Feature Ranking and the Rule Viewer.

• The Confusion Matrix calculates and visualizes the performance of any classification method by means of a plot.

• The Feature Ranking graphically displays the importance of attributes within a class and the values within specific attributes through a plot.

• The Rule Viewer is a task aimed at visually exploring rules through a plot.

Evaluation tasks can be used with the following tasks:

• Classification

• Regression

• Hierarchical basket Analysis (if the generated rules are first converted to a ruleset)

• Similar items detector (if the generated rules are first converted to a ruleset)

• Rule Manager

• LLM (as long as it contains generated rules)

Note

There is no output for the Evaluation tasks as users are not required to perform any computation for these tasks.
